How do you learn what the bytes/bits actually do?
Hello,
I am new to long coding and OBDEleven3, and I am trying to properly learn how VAG coding works instead of randomly changing things.
I have a 2025 Formentor VZ333 and in OBDEleven, I only see raw bytes and bits (bit 0-7) without labels/descriptions. SDF unlocked.
For example, I was told that Engine 01 > Byte 09 > Bit 2 is related to exhaust flaps.
Where does that information come from? I would appreciate if you could provide guides for long coding. I am just trying to actually learn how this works properly without breaking my 5-year warranty by toggling things I don't know what they are related to.
